Nice AR's. Here's my S&W M&P wearing Knight's Armament rail covers on a UTG quad rail and a junky boolsheyat Leaper's Scope.
I grew uo on AR's and something I never knew until my little jarhead brother showed me: You can drop the lower guard on the trigger by pushing the spring loaded forward detent.....allowing the user to fire with mittens on in cold weather environs. I was too busy sniping snapping turtles to notice that part.
